Abstract: A clip unit includes: an arm portion including arms extending from a proximal end portion to a distal end portion so as to be openable and closeable; a holder than can hold the arms in a closed state by accommodating the proximal end portion of the arm portion; and a thread grip attached to at least one of the arms and positioned between the arms. In a state where the arms are spread open, a dimension of the thread grip in the opening/closing direction of the arms is equal to or larger than a distance between the arms in the closed state. The thread can be elastically deformed in the closed state.

Abstract: An endoscopic treatment tool includes a sheath; a treatment portion capable of protruding and retracting from a distal end of the sheath; a manipulation main body; a slider which advances and retracts in a longitudinal axis direction to cause the treatment portion to protrude and retract from the sheath; a first locking mechanism which locks the slider at a position at which the distal end of the treatment portion is accommodated in the sheath in accordance with a retracting manipulation of the slider; a second locking mechanism provided at further distal side than the first locking mechanism and restricts advance of the slider by being locked to the manipulation main body; a fixing mechanism provided in the second locking mechanism and fixed to the manipulation main body by sliding; and a restricting portion which restricts fixing of the fixing mechanism to the manipulation main body.
